Hi Folks. There's a practice question floating around out there about advantages of using VLANS and one possible answer is that VLANS reduce the total number of switches required in a network. The common wisdom seems to be no, that's not a correct choice.
I would think yes. If I were to set up a separate physical lan for three departments that need the security of being segregated, I would need three switches at each access point. By using VLANS, I can just divvy up a single switch.
I haven't been able to find any reference to this on cisco's web site, so I'll assume the cisco answer is no. Still, I can't help but have a nagging feeling that I should select that answer if confronted with that question.
What do you guys think? Anybody taken any official cisco courses or have official cisco curriculum where this is mentioned?
